Below are from '06-'08 Service Manual. Looks pretty much like run of the mill drum brake arrangement (I have not done these on RL, but plenty of older cars). If you haven't worked on one before, be advised that w/o special spring install tools, it just takes a good bit of patience & perseverance. You'll probably be pulling with one hand & pushing with the other while things are slipping loose several times before you finally conquer the challenge. Not particularly "tricky"..... just difficult fighting the springs. Just keep at it 'til you get 'er done. A second set of hands 'might' be helpful (depends on whose hands).
